(Cl. 18S-45) 1 Claim. 1

This invention relates to new and useful improvements in means for removing moisture from air.

The principal object of the present invention is to provide an enclosure having air filtering means adapted to remove moisture to an extremely high percentage.

Another important object of the invention is to provide a moisture removing device constructed in such a manner as to permit the various parts to be quickly diassembled for the purpose of making repairs or replacements,

Other objects and advantages of the invention shall become apparent to the reader of the following description.

In the drawing- Figure 1 represents a vertical sectional view through the device.

Figure 2 is a fragmentary inside elevational view showing the air inlet.

Figure 3 is a cross section on the line 3-3 of Figure 1.

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 denotes an elongated barrel externally threaded at its upper end to accommodate an internally threaded cap 6 which has an adapter I disposed therethrough, this adapter being threaded externally at its inner end as at 8. The lower end of the barrel 5 is internally threaded to receive the externally threaded portion of a bowl 9 which has a drain cock IEI at the bottom thereof.

A fitting II, internally threaded at its upper portion, receives the threaded lower portion 8 of the adapter 'I and a strainer I2 is interposed betweenthese parts.

The tting l I has a reduced externally threaded apron I3 which engages the internal threads at the upper end of a perforated outer tube I4, this tube having openings l5.

A second or inner tube I6 has its upper end disposed into the lower portion of the tting Il and a screen Il is interposed between these parts.

A cap lil, which may be knurled at its periphery, has an externaly threaded skirt I9 disposed upwardly into the lower internally threaded end of the outer tube I4 and this skirt I9 serves to support the inner tube IB, the tube IB being formed with openings 20.

Interposed between the perforated tubes I4, I6 are several convolutions of felt 2|. Under some conditions chamois may be employed, but it is thought that felt is more satisfactory for the more thorough removal of moisture from air.

The inner tube I4 is substantially illed with a mass of steel wool ,22.

A threaded air inlet connection 23 has a hemispherical-shaped end 24 projecting into the barrel 5 and this end 25 has a pair of horizontally spaced air ports 25, 25 therein.

In the operation of the device, it can be seen that air enters the barrel 5 through the ports 25 and follows the path substantially shown by arrows in Figure 1. The air in order to get through the fitting l must pass through the openings of the tubes i4, it and in doing so has most of its moisture removed by the felt 2|. Any moisture left in the air is almost completely removed by the passing of the air through the mass of steel wool 22.

It is here further pointed out that there are many different places where the moisture remover of the present invention can be used to good advantage. For instance, it will remove the moisture from any compressed air line to which it is attached and thus allow nothing but dry air to pass through and out of the line. This is an important advantage because, ordinarily, a compressed air drum will collect moisture, and unless the moisture is removed the same will have an iniurious effect on certain utilities, especially devices or instruments of a delicate character, supplied from an air line. Furthermore, the device of the present invention prevents freezing up of air supply lines that are subject to low temperatures in use. Obviously, therefore, the moisture remover of the present invention will relieve these conditions, and it can be applied and used efciently in many and various industries.

While the foregoing description sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A moisture remover comprising a container having an air inlet, said container being provided with an outlet and a perforated hollow structure projecting inwardly of the container from the outlet, a ller of steel wool in the hollow structure, and a jacket of felt surrounding the steel wool, inner and outer perforated rigid tubes forming part of the hollow structure, said felt being interposed between the tubes, a cap at the inner ends of the tubes, said cap being threadedly secured to one tube and positioned to support the other tube.
